About me

I'm a product designer and founder, with many failures and a few small personal successes too.

You might say I'm a "serial entrepreneur." To be honest though, I'm not a big fan of "serial" anything and the label makes me cringe whenever I read it in a Twitter bio. I mention the S.E. label though, because in producing many bootstrapped & funded products I've filled the role of designer, video producer, front end developer, and minimum viable developer.

Some of my favorite projects and people that I've designed and developed with are 50 Cent, Cookpad, TenTen and my current team at 96 Problems.

    We did a small pre-launch on a Japan... continue reading (0, 1 image)

    I aspire to being a writer, which my boxing aspirations help by giving me a focus. This is a collection of personal short writings on the moments that make up boxing.

  5. First Draft focuses on making it easy to get your ideas out on paper. It’s like writing by hand or on a typewriter, not a text “editor.” That means no deleting and focusing not on the words or word smithing, but on the bigger idea and getting it out.

  6. A #1DayHack that the team and I made at 96 Problems today to make it easier for you to easily discover if other users are on Medium and what they've written. We really wanted to make something that seamlessly blends into the Twitter interface, while also staying true to Medium's... continue reading (0, 1 image)

    Just some thoughts on the creative process and getting feedback that I learned from a story told by Aziz Ansari that started out like this:

    You know this one time it was so fascinating. [Kanye] was working on Twisted Fantasy and there’s a guy that comes in he’s... continue reading (0, 1 image)
